I live on one acre, with a cement block wall surrounding our yard. I am surrounded by neighbors. My town has zero restrictions on farm type critters (which is pretty cool!). I am interested in getting guineas to try to help out with the cockroach and scorpion population. I do have a garden with fruits, veggies, and herbs. I also have two dogs. One Australian Shep. (who is wonderful with the chickens...doesn't chase them, and when he's outside he chases off the wild birds trying to get their feed) and one Labrador Ret. (who has killed two of my chickens, but has been around a friend's guineas before and left them alone). My main worry would be the guineas escaping the yard, and my one dog. I can control the dog...but don't think I can control guineas that think the grass is greener on the other side. So, should I bother giving it a try?
